Part of FeatureVariations

Fields

condition_set_offset: BigEndian<Nullable<Offset32>>

Offset to a condition set table, from beginning of FeatureVariations table.

feature_table_substitution_offset: BigEndian<Nullable<Offset32>>

Offset to a feature table substitution table, from beginning of the FeatureVariations table.

Implementations

impl FeatureVariationRecord

pub fn condition_set_offset(&self) -> Nullable<Offset32>

Offset to a condition set table, from beginning of FeatureVariations table.

pub fn condition_set<'a>( &self, data: FontData<'a> ) -> Option<Result<ConditionSet<'a>, ReadError>>

Offset to a condition set table, from beginning of FeatureVariations table.

The data argument should be retrieved from the parent table By calling its offset_data method.

pub fn feature_table_substitution_offset(&self) -> Nullable<Offset32>

Offset to a feature table substitution table, from beginning of the FeatureVariations table.

pub fn feature_table_substitution<'a>( &self, data: FontData<'a> ) -> Option<Result<FeatureTableSubstitution<'a>, ReadError>>

Offset to a feature table substitution table, from beginning of the FeatureVariations table.

The data argument should be retrieved from the parent table By calling its offset_data method.
